ALSA: fm801: Remove always NULL parameter

snd_fm801_pcm() takes a pointer to a pointer of a PCM where if this parameter is provided the newly allocated PCM is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit cleaner and shorter. Signed-off-by: Lars-Peter Clausen <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>
